The type of research conducted was experimental about the effectiveness testing of urang aring leaf various concentrations extract on Pediculus humanus capitis mortality. 125 adult Pediculus humanus capitis were taken by using Random sampling method. The results were a 5% concentration had an average mortality of 2.6 (53.33%) or about 2-3 heads. The 25% concentration averaged 3.5 (70%) deaths or about 3-4 heads. Concentration 50% average mortality 4.5 (90%) or about 4-5. Concentration 100% average mortality 5 (100%) or all dead. Urang aring extract in this rsearch is effective in killing Pediculus humanus capitis and the most optimal concentration is 100% concentration.]]>
